Cannot interact with github.com after adding cookie prefix support
After 8d85d110, it's no longer possible to interact with github.com using Ephy Tech Preview. I cannot post comments, change notification settings, etc. I see errors in the web inspector:
[Error] Failed to load resource: the server responded with a status of 422 (Unprocessable Entity) (comment, line 0)
A workaround is to delete my GitHub login cookie, then sign in to GitHub again. Then it will work only until I restart Epiphany.
